Abstract: Certain example embodiments provide systems, methods, apparatuses, and computer program products for control short control signal (SCS) in downlink. For example, certain embodiments may provide for a method examining whether a signal to be transmitted by a network element belongs to a first group or to another group based on a transmission time instance of the signal, a beam or beams of the signal, a beam index or beam indices of the signal and/or a type of the signal; determining an allowance of time or resources of a time period for one or more short control signals; determining whether to transmit the signal as one or more short control signals based on the group the signal belongs to and on the allowance; and transmitting the signal either as one or more short control signals, or as a signal subject to listen before talk procedure.

Abstract: Certain example embodiments provide systems, methods, apparatuses, and computer program products for control short control signal (SCS) in uplink. For example, certain embodiments may provide for regulating the amount of uplink (UL) transmissions in a cell, such that SCS limitations are not violated. Certain embodiments may relate to a situation where a single SCS allowance or multiple SCS allowances may be in use in the cell and, e.g., a single SCS allowance may be shared between a gNB and the UEs, or a single SCS allowance may be shared between the UEs.

Abstract: Systems, methods, apparatuses, and computer program products for dynamic transmit diversity fallback are provided. One method may include configuring a user equipment with a maximum number of multiple-input multiple-output (MIMO) layers used for transmission mode 9 or transmission mode 10 scheduling, and performing, by a network node, at least one of transmission mode 9 or transmission mode 10 scheduling. The configuring may include indicating to the user equipment to use a modified mapping table providing transmit diversity fallback for the at least one of transmission mode 9 or transmission mode 10 scheduling.

Abstract: It is provided a method, comprising checking if an option grant for an uplink transmission is received, wherein the option grant comprises, for a subframe, a first allocation option to start the uplink transmission and a second allocation option to start the uplink transmission, wherein the first allocation option is earlier in the subframe than the second allocation option; deciding if the uplink transmission is allowed at the first allocation option; starting the uplink transmission at the first allocation option if the option grant is received and the uplink transmission is allowed at the first allocation option; deciding if the uplink transmission is allowed at the second allocation option; starting the uplink transmission at the second allocation option if the option grant is received, the uplink transmission is not allowed at the first allocation option, and the uplink transmission is allowed at the second allocation option.

Abstract: A technique includes receiving, by a user device from a base station, a first message indicating a plurality of sets of uplink control channel resources for the uplink transmission of a type of uplink control information, each set of uplink control channel resources having a resource configuration; receiving, by the user device from the base station, a second message that is different from the first message, the second message indicating a selected uplink control channel resources, of the plurality of sets of uplink control channel resources, for the uplink transmission of a type of uplink control information; and sending, by the user device to the base station, uplink control information via the selected set of uplink control channel resources.

Abstract: A method and an apparatus for a second user equipment, that causes the apparatus to perform: determining whether a synchronization signal has been received during a first set of synchronization resources; and when it is determined the synchronization signal was received, determining that the apparatus is allowed to use communication resources during a second set of synchronization resources for a first sidelink communication; and when it is determined the synchronization was not received, abstaining from using the communication resources during the second set of synchronization resources for a first sidelink communication; and monitoring the second set of synchronization resources for a synchronization signal.

Abstract: Systems, methods, apparatuses, and computer program products for multi-slot physical downlink control channel (PDCCH) monitoring. A method may include determining that a search space relates to a subcarrier spacing and to multi-slot physical downlink control channel monitoring. The method may also include receiving a search space information element that defines a bitmap that defines a number of slots with monitoring occasions. The method may further include receiving a duration parameter that defines a length of a monitoring window. In addition, the method may include determining actual monitoring slots for each period of the monitoring window. Further, the method may include monitoring a physical downlink control channel corresponding to the search space based on the defined duration parameter.

Abstract: A technique, comprising: storing, at a user equipment, information about a sequence of uplink grants for the user equipment to make uplink transmissions via one or more radio channels of a plurality of unlicensed radio channels; and in response to data becoming transmission-ready at the user equipment with one or more intervening uplink grants before the earliest opportunity to attempt to transmit the data via a first unlicensed radio channel currently activated at the user equipment, activating a second unlicensed radio channel, and attempting to transmit the data via the second unlicensed radio channel at an uplink grant of the one or more intervening uplink grants.
